Normal Operation and Fault Conditions
The wake-up control circuit wakes up the PCM and the SOBDMC / TCM prior to engine cranking/torque request. The PCM and SOBDMC / TCM needs to wake up prior to a crank/torque request so they have the time to go through their initialization. The wake-up control circuit is controlled by the BCM .
The BCM activates the wake-up control circuit when any of the following occur
- The driver door is opened
- A key is inserted into the ignition
- The ignition is in the ON or START position

DTC FAULT TRIGGER CONDITIONS
The BCM controls the output of several vehicle systems by means of solid state drivers. When an overload occurs on any of these drivers, the BCM disables the output and tracks the number of repetitive faults on each of these circuits. The module compares this number of overloads to 3 progressive thresholds established for each circuit. At each threshold, DTC U1000:00 sets along with the DTC associated with the affected circuit.
